Natural menopause timing and menopause symptoms among lesbian, bisexual, and heterosexual women in the Nurses' Health Study II.

Objective: This study aimed to examine sexual orientation differences in natural menopause timing and symptoms between lesbian and bisexual women compared with heterosexual women.

Methods: We used longitudinal questionnaire data (1989-2015) from 92,314 women (858 lesbian, 375 bisexual) in the Nurses' Health Study II cohort. Women were 24-44 yr old at baseline and biennially reported their menopause status, including reasons for cessation of menstrual periods.

A National Survey of Obstetrics and Gynecology Resident Perspectives on Their Preparedness to Provide Care for Underserved Patients with Gynecologic Malignancies.

Obstetrics and Gynecology (Ob/Gyn) residents will encounter, screen for, and diagnose gynecologic malignancies. This survey assessed residents' confidence in providing NCCN Guidelines-based care to Gynecologic Oncology patients of differing racial/ethnic backgrounds and insurance statuses while accounting for residents' backgrounds. An anonymous, novel Qualtrics survey was disseminated to current US Ob/Gyn residents, with multiple-choice questions about subject demographics and Likert scale questions about their readiness to care for diverse patients.

The Impact of a Lifestyle Intervention on Cardiometabolic Risk Factors among Postpartum Hispanic Women with Overweight and Obesity in a Randomized Controlled Trial (Proyecto Mamá).

Introduction: Maternal overweight or obesity has been associated with metabolic syndrome through 1 year postpartum, but it remains unknown whether a culturally-modified, motivationally-targeted, and individually-tailored Lifestyle Intervention could improve postpartum cardiometabolic health among Hispanic women with overweight or obesity.

Methods: Proyecto Mamá was a randomized controlled trial conducted in Western Massachusetts from 2014 to 2020 in which Hispanic women with overweight/obesity were randomized to a Lifestyle Intervention (LI) involving diet and exercise or to a comparison Health and Wellness Intervention (HW). Biomarkers of cardiovascular risk (i.

Bothersome symptoms at midlife in relation to body fat percentage.

Objectives: Increasing obesity has been associated with a higher frequency of symptoms at midlife. Bothersomeness represents an important measure of perceived symptom severity, but has received relatively little consideration, and relationships between symptom bothersomeness and obesity are not known. We evaluated the association between body fat percentage (%BF) and the bothersomeness of symptoms at midlife.

The impact of a lifestyle intervention on postpartum weight retention among US Hispanic women with overweight and obesity.

Introduction: To evaluate the effect of a culturally-modified, motivationally-targeted, individually-tailored lifestyle intervention on postpartum weight retention among Hispanic women with overweight/obesity.

Materials And Methods: Proyecto Mamá was a randomized controlled trial conducted in western Massachusetts (2014-2020). Hispanic women with overweight/obese pre-pregnancy BMI (n = 148) were randomized in early pregnancy to a Lifestyle Intervention (LI) or a Health & Wellness (HW) comparison arm.

Association of platinum-based chemotherapy with live birth and infertility in female survivors of adolescent and young adult cancer.

Objective: To estimate the effect of platinum-based chemotherapy on live birth (LB) and infertility after cancer, in order to address a lack of treatment-specific fertility risks for female survivors of adolescent and young adult cancer, which limits counseling on fertility preservation decisions.

Design: Retrospective cohort study.

Setting: US administrative database.

The Impact of a Lifestyle Intervention on Postpartum Cardiometabolic Risk Factors Among Hispanic Women With Abnormal Glucose Tolerance During Pregnancy: Secondary Analysis of a Randomized Trial.

Background: Women with abnormal glucose tolerance during pregnancy are at risk for cardiovascular disease (CVD), with higher rates among Hispanics. However, studies on the impact of lifestyle interventions on postpartum CVD profiles are sparse.

Methods: This is a secondary analysis of a controlled trial among a subsample of Hispanic women with abnormal glucose tolerance participating in Estudió PARTO (Project Aiming to Reduce Type twO diabetes; mean age = 28.

Non-coding RNAs from seminal plasma extracellular vesicles and success of live birth among couples undergoing fertility treatment.

Infertility remains a global health problem with male-factor infertility accounting for around 50% of cases. Understanding the molecular markers for the male contribution of live birth success has been limited. Here, we evaluated the expression levels of seminal plasma extracellular vesicle (spEV) non-coding RNAs (ncRNAs) in men of couples in relation with those with and without a successful live birth after infertility treatment.

Urinary phthalate metabolites and small non-coding RNAs from seminal plasma extracellular vesicles among men undergoing infertility treatment.

Non-coding RNA (ncRNA) cargo of extracellular vesicles (EVs) in the male reproductive tract play critical roles in semen quality and emerging evidence suggests their susceptibility to environmental factors. Male phthalate exposures have been linked to poor semen quality, sperm DNA methylation profiles and embryo development; however, there is limited evidence on their potential impact on EV ncRNAs profiles. We evaluated the association between urinary phthalate metabolites and small ncRNAs (sncRNAs) of seminal plasma EVs (spEV) among men receiving clinical infertility care.

Maternal comorbidity and adverse perinatal outcomes in survivors of adolescent and young adult cancer: A cohort study.

Objective: To evaluate risks of preterm birth (PTB) and severe maternal morbidity (SMM) in female survivors of adolescent and young adult cancer and assess maternal comorbidity as a potential mechanism. To determine whether associations differ by use of assisted reproductive technology (ART).

Design: Retrospective cohort.

Preconception sleep duration, sleep timing, and shift work in association with fecundability and live birth among women with a history of pregnancy loss.

Objective: To evaluate the associations between preconception sleep characteristics and shift work with fecundability and live birth.

Design: Secondary analysis of the Effects of Aspirin in Gestation and Reproduction study, a preconception cohort.

Setting: Four US academic medical centers.

Racism-Related Experiences and Adiposity: Findings From the Black Women's Experiences Living With Lupus (BeWELL) Study.

Introduction: Studies suggest that higher rates of excess adiposity in Black women may in part be driven by experiences of racism. Racial microaggressions, which include unintentional and subtle slights and insults, and responses to racism such as racism-related vigilance, may contribute to adiposity in this population. This study examined these understudied racism-related facets as well as interpersonal racial discrimination in relation to adiposity in a cohort of Black women with systemic lupus erythematosus.

Association of adverse pregnancy outcomes and multiple gestation with natural menopause: A population-based cohort study.

Objective: Adverse pregnancy outcomes (APOs) and early menopause are each associated with increased risk of cardiovascular disease (CVD); whether APOs are associated with age at menopause is unclear. We examined the association of gestational diabetes (GDM), hypertensive disorders of pregnancy (HDP), preterm birth, and multiple gestation with age at natural menopause.

Study Design: Observational, prospective study within the Nurses' Health Study II cohort (1989-2019).

Limited evidence of a threshold effect for increasing adiposity on risk of symptoms at midlife.

Objective: To assess the nature of relationships between increasing body mass index (BMI) and the prevalence of midlife symptoms in a population with high adiposity.

Methods: In the cross-sectional Study of Women's Health in Qatar, 841 participants aged 40 to 60 years were recruited from nine primary health centers in Doha. Face-to-face interviews collected demographic, menopause, and symptom information.

Altered non-coding RNA profiles of seminal plasma extracellular vesicles of men with poor semen quality undergoing in vitro fertilization treatment.

Background: Currently, the precise mechanisms that underline male infertility are still unclear. Accumulating data implicate non-coding RNA cargo of seminal plasma extracellular vesicles due to their association with poor semen quality and higher expression levels relative to vesicle-free seminal plasma.

Method: We assessed sperm-free seminal plasma extracellular vesicle non-coding RNA profiles from 91 semen samples collected from male participants of couples seeking infertility treatment.

Urinary phthalate metabolites and their mixtures are associated with advanced sperm epigenetic aging in a general population.

Introduction: We have recently shown that sperm epigenetic age (SEA), a surrogate measure of biological aging in sperm, is associated with couples' time-to-pregnancy (TTP). Advanced SEA was also observed among smokers, suggesting its susceptibility to environmental exposures. Therefore, we assessed the association between urinary phthalate metabolites and SEA in male partners of couples planning to conceive among the general population.

The association between anthropometric factors and anti-Müllerian hormone levels in premenopausal women.

Adiposity has been associated with several health conditions as well as timing of menopause. Prior epidemiologic studies on the association of adiposity and anti-Müllerian hormone (AMH) have been inconsistent. We evaluated the relations of anthropometric measures with AMH at two time periods in a subset of premenopausal participants in the Nurses' Health Study II.
